After being selected No. 50 overall in the 2011 NBA draft, Allen became a fan favorite for a Sixer team in desperate need of some production in the frontcourt.

Although he only averaged 4.1 points and 4.2 rebounds per game throughout the season, Allen's performances in place of the injured Spencer Hawes and Elton Brand were integral to the Sixers' surprising success.

However, Allen would truly shine in the playoffs. Allen upped his points per game total to 6.3, playing nearly 20 minutes per game.

By extending Allen, the 76ers' front office has placed trust in a player who entered the NBA with extremely low expectations. Alongside rookie Arnett Moultrie, Allen should be a staple of the Sixers' frontcourt for years to come.

Next up for the Sixers is determining the fate of Brand—long thought to be a prime candidate for the team's amnesty clause.
